Just got a Sega Saturn and loving it. I just learned about a little secret in Daytona USA-- you can unlock a horse and race it around the tracks. I couldn't find any decent videos of it here on Youtube, so I decided to make one of my own.
To those who are wondering: you can unlock this one of two ways: 1. at the title screen hold up & left (diagonally), A, B, X, and Z, and press start. 2. Win every race in Saturn mode on normal difficulty.
Gosh, I'm not really that good at this game.
(Apologies for recording it off the screen, but my old video capture device doesn't seem to work any more. If I fix it, or get a new one, I'll make a better video.)
